Objective
To appraise the principles and methodologies used in Plant Pathology

Theory

UNIT I
Importance, definitions and concepts of plant diseases, history and growth of plant pathology, biotic and abiotic causes of plant diseases, disease caused by phanerogamic parasites

UNIT II
Growth, reproduction, survival and dispersal of important plant pathogens, role of environment and host nutrition on disease development, modern detection methods.

UNIT III
Host parasite interaction, recognition concept and infection, symptomatology, disease development- role of  enzymes, toxins, growth regulators; defense strategies- oxidative burst; Phenolics, Phytoalexins, PR proteins, Elicitors, induced resistance, Altered plant metabolism as affected by plant pathogens.

UNIT IV
Genetics of resistance; ‘R’ genes; mechanism of genetic variation in pathogens; molecular basis for resistance; marker-assisted selection; genetic engineering for disease resistance.

UNIT V
